CONDENSER FQR EXHAUST-STEAM.

SPECIFICATION forming part of Letters Fatent No. 515,874, dated March 6,1894. Applicationfiled December 29, 1893. Serial No. M95391. (No model.)

'TO all whom it may concern:

Be it known that I, J AMES A. DILLON, a citizen of the United States,residing at T0- ledo, in the county of Lucas, State of Ohio, haveinvented certain new and useful Improvements in Condensers forExhaust-Steam, of which the following is a specification, referencebeing had therein to the accompanyin g drawings.

This invention relates to certain new and useful improvements incondensers for exhaust steam, and it has for its objects among others toprovide a simple and cheap condenser which can be applied either inclose proximity to the engine or boiler or at a distance therefrom, andby the use of which the steamwill be nearly all condensed and theobjectionable noise heretofore accompanying the exhaust obviated. Thedevice embodies a casing having a tapered lower portion and acentrally-disposed tubular outlet for the dry steam and provided withdeflecting plates, a perforated ring being arranged around the lower endof the said central tube and connected with a source of cold water. Twoinlet connections are provided into the cylinder or casing, onefor ahorizontal connection with the exhaust, as when the device is arrangednear the engine or boiler and the other for a vertical connection aswhen the device is placed upon the roof or outside the building, thecentral tube being of a greater or less length according to the locationof the device. The steam is forced to come into contact with the coldwater before it can pass out the central tube, and any steam that is notdried before it enters the said central tube will be retarded andcondensed by the plates within the tube.

Other objects and advantages of the invention will hereinafter appearand the novel features thereof will be particularly defined by theappended claims.

The invention is clearly illustrated in the accompanying drawings,which, with the letters of reference marked thereon, form a part of thisspecification, and in which- Figure lis a central vertical sectionthrough my improved condenser. Fig. 2 is a cross section through thesame on the line 2-2-of Fig.

1 looking upward. Fig. 8 is a cross section on line 3-3 of Fig.1,1ooking down.

Like letters of reference indicate like parts throughout the severalviews.

Referring now to the details of the drawings by letter, A designates thebody portion which is composed of any suitable material, and preferablyin two parts the upper one of which is cylindrical in form and having atop a, preferably somewhat dome-shaped as seen in Fig. 1, and thefunnel-shaped part A having a lateral flange ct as seen in Fig. 1 uponwhich rests the portion A, the flange a of the lower part extending upwithin the upper part and frictionally held thereon. The lower taperedportion terminates in the discharge tube A through which the water ofcondensation escapes.

B is an inlet noarthe upper end of the body portion, designed for aconnection, say horizontal, with the exhaust pipe, not shown, when thedevice is placed near the boiler or engine, and O is another inletextending upward through the inclined side of the lower portion to admitsteam by suitable connection with the exhaust, for instance when thedevice is placed outside the building, as on the roof. The pipe B ispreferably arranged tangentially as seen in Fig. 2 so as to introducethe steam in such a manner as to cause a circular motion of the samewithin the interior of the device. p

D is a tube held concentrically within the device and its lower endextending into the tapered portion thereof as seen in Fig. 1. Its lowerend is open and its upper end extends through the top of the bodyportion to any required distance, depending upon the location of thecondenser. Within this tube is a number, more or less, of invertedtruncated cone shaped plates D which serve as means for condensing thesteam which may enter the tube not dry, and which serve also to re tardthe movement of the steam in its upward passage.

E is a ring surrounding the lower end of the tube and having a lateralextension E designed to be connected with some source of cold watersupply. This ring is perforated upon its upper face as seen best in Fig.3 so as to distributethe water in the form of spray laterally so thatthe steam must of necessity come in contact therewith in its passage tothe central tube. The ring may be supported in any suitable manner.

With the parts constructed and arranged substantially as above setforththe operation is as followsz-The device is connected with theexhaust by either of the pipes B or O as the case may be, the otherbeing closed in any suitable manner, as by a removable cap d shown ontheend of the pipe B in Fig. 1, and

the cold water is allowed to flow through the connection E into the ringE from which it discharges in small streams or spray as seen in Fig. 3;the steam must of necessity pass in contact with this spray by which itis'con densed and the dry steam passes up the central tube and out, andwater remaining therein being condensed by the plates D within saidtube. The water passes out through the discharge A to anysuitable placeof deposit.

What I claim as new is I p 1. The combination with the body portion, ofa steam inlet thereto, a centrally-disposed tube with its lower endextended below the steam inlet, and a water spraying device near thelower end of said tube, as set forth.

2. A condenser consisting of a body portion with steam inlet, acentrally-disposed tube, 30 plates within the tube, and a perforatedwater ring near the lower end of the tube, substantially as specified. 7

3. The combination with a body portion having funnel-shaped lowerportion, of the 5 steam inlet near the upper end of the same, thevertical steam inlet, the central tube, and the perforated ring aroundthe lower end of the tube, substantially as specified.

4. The herein described condenser, consisto ing of the body portion oftwo parts each having a steam inlet and the lower portion beingfunnel-shaped and terminating in a discharge tube, thecentrally-disposed tube extending into the tapered portion and throughthe top 45 of the body, the inverted truncated coneshaped plates withinthe tube, and the perforated ring around the lower end of the said tubeand having a lateral extension for connection with a water supply,substantially as 50 specified.

In testimony whereof I affix my signature in presence of two witnesses.

JAMES A. DILLON.
